commit 0d4438368fd769a0e6b83bfdaf1cb980f888c504 Author: Iswarya_Vakati <v.iswa...@nectechnologies.in> Date: Sat Sep 17 17:07:16 2016 +0530 Don't attempt to escalate manila-manage privileges Remove code which allowed manila-manage to attempt to escalate privileges so that configuration files can be read by users who normally wouldn't have access, but do have sudo access.

This isn't a full security audit. This looks like trouble: ./designate/cmd/manage.py def main(): CONF.register_cli_opt(category_opt) try: utils.read_config('designate', sys.argv) logging.setup(CONF, 'designate') except cfg.ConfigFilesNotFoundError: cfgfile = CONF.config_file[-1] if CONF.config_file else None if cfgfile and not os.access(cfgfile, os.R_OK): st = os.stat(cfgfile) print(_("Could not read %s. Re-running with sudo") % cfgfile) try: os.execvp('sudo', ['sudo', '-u', '#%s' % st.st_uid] + sys.argv) except Exception: print(_('sudo failed, continuing as if nothing happened')) print(_('Please re-run designate-manage as root.')) sys.exit(2) This is an interesting decision -- if the configuration file is _not_ readable by the user in question, give the executing user complete privileges of the user that owns the unreadable file. I'm not a fan of hiding privilege escalation / modifications in programs -- if a user had recently used sudo and thus had the authentication token already stored for their terminal, this 'hidden' use of sudo may be unexpected and unwelcome, especially since it appears that argv from the first call leaks through to the sudo call. Is this intentional OpenStack style? Or unexpected for you guys too? (Feel free to make this public at your convenience.)
